In mid 2002 I built this prototype for fun, while working on my city. I'm not really a "train head" (I only own one train set) but I thought it would be neat to try to simulate the Manhattan subway system, since most stations have the same basic look. In retrospect, I should have added some rats. :)

Again, this is just a prototype. I'd like to build a real subway system under my city, but for now this is all I did.

Here you can see all three levels. The street is on the top. The mezzaine (middle) is where you swipe in, buy tokens, and transfer from line to line. The platform level (bottom) is where you board the trains. There is an uptown plaform and a downtown platform, each serving an express (inner) track and a local (outer) track.
